[0002] The screening device uses a vibration motor as an excitation source, and transmits its acting force to the screen mesh, so as to realize the screening of materials with different particle sizes. The traditional screening device is composed of multiple groups of outer shells and screen meshes combined in a "stacked cake" manner. Among them, the screen mesh is clamped between adjacent outer shells and fixed by a clamp. When it is necessary to take out the screen mesh for cleaning and maintenance, it is necessary to remove the outer shells and screen meshes one by one from top to bottom, making the maintenance method too cumbersome. Content of the Utility Model

The upper and lower ends of the outer shell are respectively connected with an upper cover and a vibrating disk through clamps. The bottom of the vibrating disk is connected with a vibration motor, and the vibrating disk is connected to the base through a spring. The upper cover is provided with a feed inlet. The two sides of the outer shell are respectively provided with a waste outlet, a discharge outlet and a cleaning outlet. The outer shell is provided with a fine screen mesh inclined downward in the direction of the discharge outlet, and the fine screen mesh is arranged between the discharge outlet and the cleaning outlet. A coarse screen mesh is connected between the outer shell and the fine screen mesh, and the coarse screen mesh is arranged between the waste outlet and the discharge outlet.

[0004] By adopting the above technical solution, plastic particles enter through the feed inlet, and through the screening of the coarse screen mesh, the large-particle coarse materials are discharged from the waste outlet. The required plastic particles flow out from the discharge outlet along the upper surface of the fine screen mesh, while part of the small-particle impurities such as dust pass through the fine screen mesh and flow out from the cleaning outlet, so as to realize the rapid screening of plastic particles. When it is necessary to clean the screen mesh, the coarse screen mesh and the fine screen mesh can be taken out after removing the upper cover, maintaining the stability of the structure of the screening device and improving the convenience when cleaning and maintaining the screen mesh.

[0005] The utility model is further arranged such that the outer shell is respectively provided with a mounting strip, a clamping strip and a bottom inclined surface from top to bottom. The clamping strip and the bottom inclined surface form a clamping groove. One end of the fine screen mesh is clamped between the outer shell and the upper cover, and the other end is clamped in the clamping groove. The fine screen mesh is provided with a mounting part. The two ends of the coarse screen mesh are respectively connected to the mounting part and the mounting strip. During installation, one end of the fine screen mesh is clamped in the clamping groove, and the other end is placed flat between the outer shell and the upper cover, and the fine screen mesh is clamped in the outer shell through a clamp. The overall structure is simple and the screen mesh is easy to disassemble and assemble.

When the vibrating motor operates, through the buffering effect of the springs around the vibrating plate, the force exerted by the vibrating plate on the base is reduced, and abnormal noises at the connection between the base and the vibrating plate are avoided.

[0007] The present utility model is further configured such that threaded holes are provided at both ends of the installation portion, copper studs are provided at both ends of the installation strip, both ends of the coarse sieve mesh are threadedly connected to the installation portion and the installation strip, and the four corners of the coarse sieve mesh are respectively threadedly connected to the installation portion and the installation strip through screws, so that a stable triangular structure is formed between the inner wall of the outer shell, the coarse sieve mesh, and the fine sieve mesh.

[0008] The present utility model is further configured such that rubber layers are wrapped around the peripheries of the fine sieve mesh and the coarse sieve mesh, and rubber layers are adhered to the edges of the fine sieve mesh and the coarse sieve mesh. The rubber layers are connected to the outer shell to achieve a buffering effect and avoid generating noises.

[0009] The present utility model is further configured such that a positioning strip for supporting the fine sieve mesh is provided at the installation portion of the outer shell.

The upper and lower ends of the housing 1 are respectively connected with an upper cover 2 and a vibrating disk 3 through clamps. The bottom of the vibrating disk 3 is connected with a vibrating motor 5, and the vibrating disk 3 is connected to the base 6 through a spring 4. The upper cover 2 is provided with a feed inlet 100. The two sides of the housing 1 are respectively provided with a waste outlet 200, a discharge outlet 300 and a cleaning outlet 400. The housing 1 is provided with a fine sieve mesh 7 inclined downward in the direction of the discharge outlet 300, and the fine sieve mesh 7 is arranged between the discharge outlet 300 and the cleaning outlet 400. A coarse sieve mesh 8 is connected between the housing 1 and the fine sieve mesh 7, and the coarse sieve mesh 8 is arranged between the waste outlet 200 and the discharge outlet 300.

[0021] Combined with Figures 3 - 5 shown, in this embodiment, the housing 1 is respectively provided with a mounting strip 11, a clamping strip 12 and a bottom inclined surface 13 from top to bottom. The clamping strip 12 and the bottom inclined surface 13 form a clamping groove 14. One end of the fine sieve mesh 7 is clamped between the housing 1 and the upper cover 2, and the other end is clamped in the clamping groove 14. The fine sieve mesh 7 is provided with a mounting portion 15. The two ends of the coarse sieve mesh 8 are respectively connected to the mounting portion 15 and the mounting strip 11. During installation, one end of the fine sieve mesh 7 is clamped in the clamping groove 14, and the other end is placed flat between the housing 1 and the upper cover 2. The fine sieve mesh 7 is clamped in the housing 1 through a clamp. The overall structure is simple and the sieve mesh is easy to disassemble and assemble.

[0022] In this embodiment, the upper and lower ends of the housing 1 are provided with bending portions 16 for installing clamps. The upper cover 2 / vibrating disk 3 is provided with a protruding portion 17 corresponding to the bending portion 16. The bottom of the vibrating disk 3 is provided with receiving grooves 18 distributed in a circumferential manner. One end of the spring 4 is fixedly connected to the base 6, and the other end abuts against the receiving groove 18. When the vibrating motor 5 works, through the buffering action of the springs 4 around the vibrating disk 3, the acting force of the vibrating disk 3 on the base 6 is reduced, and abnormal noise at the connection between the base 6 and the vibrating disk 3 is avoided.

[0023] In this embodiment, threaded holes are provided at both ends of the mounting portion 15, copper studs 19 are provided at both ends of the mounting strip 11, and both ends of the coarse screen 8 are threadedly connected to the mounting portion 15 and the mounting strip 11.

[0026] The working principle of the present utility model is that when the vibration motor 5 operates, the housing 1 is guided to vibrate as a whole through the vibration disk 3. When plastic particles enter through the feed port 100, they preferentially flow along the fine screen 7 to the coarse screen 8. Through the screening of the coarse screen 8, large-particle coarse materials are discharged from the waste outlet 200, and the required plastic particles flow out from the discharge port 300 along the upper surface of the fine screen 7. During this period, small-particle impurities such as some dust can directly pass through the fine screen 7 and flow out from the cleaning port 400, thereby realizing the rapid screening of plastic particles.

Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
